20 Original Motivation Research community s desire to be able to experiment with new control paradigms Base Assumption Providing reasonable abstractions for control requires the control system topology to be decoupled from the physical network topology OpenFlow was designed to facilitate separation of control and data planes in a standardized way Current OpenFlow specification defines an abstract flow-based switch model (OpenFlow switch) and a standardized interface (OpenFlow protocol) OpenFlow switch: An abstraction of an Ethernet switch; currently focused on Forwarding abstraction OpenFlow protocol: A communication protocol that provides access to the forwarding plane of an OpenFlow switch 2013 Cisco and/or its affiliates.
